  • Publication number: 20230017763
    Abstract: A haemostatic device for treating post-operative bleeding of the prostatic cavity, having a body or catheter having a first canal in fluidic communication with a first inflatable balloon formed on the body. The balloon and canal are positionable inside the bladder against the back of the bladder and configured to apply a determined pressure, in the inflated state, on the prostatic cavity to block off and isolate the prostatic cavity, to reduce its volume and to occlude the blood vessels in its cavity wall. The body includes a second canal fluidically connected to a second balloon, extend in the prostatic cavity while conforming to the irregularities of the prostatic cavity. The device has a tensioning tube for easy insertion of the penis in the flaccid state, without compressing the walls of the penis or the glans, having a longitudinal slot extending between two ends of the tensioning tube.

  • Patent number: 9517120
    Abstract: A device for positioning a stent in a natural canal after passing through an obstacle at the level of a target organ. The device includes a stent, a pusher tube, and a guide. The guide is configured to push the stent through the lumen of the natural canal, and includes at least one flexible part having a predetermined longitudinal stiffness and a lateral flexibility that allow a reversible deformation from a straight position to a bent position so as to follow the curve of the natural canal under the application of minimal external forces exerted by an operator. The device is particularly adapted to the technical field of urology.

  • Patent number: 8211085
    Abstract: Therapeutic device intended for the selective cytoreductive treatment of an obstruction in a natural lumen or passage of the human or animal body, said lumen being obstructed by the effect of a local cell proliferation, said device comprising a tubular element, in particular of cylindrical shape, intended to be placed in said natural lumen and sufficiently flexible to conform to said natural lumen, but sufficiently rigid to maintain an artificial channel in said lumen. The tubular element supports lengthwise a medicinal sleeve which is intended to come into line with, and into contact with, the obstruction once the natural lumen has been intubated, and is designed to deliver locally, at least in its outer surface portion, at least one therapeutic agent which is cytoreductive, in particular cytotoxic, through contact with the cells under whose effect said lumen is obstructed.

  • Publication number: 20090299488
    Abstract: The invention concerns a prostatic stent including a flexible tubular member having a lateral wall equipped with anchoring means, adapted for anchoring the prostatic stent into the urethra, wherein the anchoring means includes a succession of hollow and projecting elements defining a continuous and smooth anchoring profile, thereby forming an anchor for the prostatic stent in place into the urethra, and adapted to avoid any lesion of the urethra during insertion or withdrawal of the stent.

  • Publication number: 20060122709
    Abstract: A prosthesis intended for the treatment of a natural lumen or tract of a human or animal body through which a flow is effected on either side of a sphincter is disclosed. The prosthesis comprises at least one tubular element, in particular of cylindrical shape which is sufficiently flexible to conform to the natural lumen, but sufficiently rigid to maintain an artificial passage in the lumen, and is intended to be placed in the natural lumen. The wall of the tubular element comprises a relatively smooth and soft biocompatible material, such as silicone rubber, at least in its outer part.

  • Publication number: 20030199988
    Abstract: A stent device and methods for inserting and removing a stent to and from an anatomical tract of a living being. The stent includes a distal segment and a proximal segment joined by a flexible connection structure. The stent is inserted using components comprising a delivery assembly such that the stent proceeds through the anatomical tract and seats the flexible connection structure of the stent in a natural constricting structure of the anatomical tract. The flexible quality of the connection structure permits the natural constricting functions of the anatomical tract to occur. The natural closure of the anatomical constricting structure stops the flow of fluid, for example, from a target organ which indicates that the stent is properly placed within the anatomical tract.

  • Patent number: 5876417
    Abstract: A detachable catheter apparatus that conveys a fluid includes a tube assembly and an insertion device. The tube assembly extends along a longitudinal axis and includes a distal tube section having a closed end and an opposite opened end, a proximal tube section having a first end and an opposite second end and a connector fabricated from a flexible, deformable material. The connector connects the opened end of the distal tube section and the first end of the proximal tube section together. The distal tube section includes an orifice formed therethrough and sized to enable fluid to enter the distal tube section so that the fluid can flow into and through the distal tube section, the connector and the proximal tube section. The insertion device is slidably receivable by the tube assembly, and includes an elongated inner alignment rod having a contact end portion and an insertion end portion disposed opposite the contact end portion.
